Why the wrench is flourescent orange ...

During high school, Jos did volunteer bicycle repair in East Palo Alto. Volunteers had to supply their own tools. Like many mechanics, he found his tools slowly disappearing. To combat accidental acquisition, Jos spray-painted his tools with bright orange paint. Tools stopped wandering after that.

However, one drawback of this procedure arose --- the socket wrench did not like paint gumming up its works. It took disassembly, a long soak in paint thinner, and relubrication to fix the problem.
